This little project we use We use four magnets to suspend the rotor in the air,Four solar panels,Produce electricity(each produce about 160ma,0.5v) under sunlight,Current through coil,Rotating in a magnetic field

The principle is simple, that is, the electric current passes through the coil, and the coil is subjected to the action of the magnetic field,By means of a specific winding method,then rotate

Can’t wait to know how to make it? Let’s get started!

first remember this

the picture above tell you the Basic principle,Think seriously,Although a lot of Mendocino motor shape is different, but it is the same principle

Step1

Step2

2 magnets are mutually exclusive,and Install in the same direction,And make sure it’s also exclusive to the small magnets

It’s best to use a quick drying gel,Because the magnets are mutually exclusive, if the glue dries slowly, then you need to hold it until the magnets are fixed

hold it until fixed

ok,the base finished

now let us make the Revolving body

it is a little complex,Because to keep rotate, you need to follow a specific order to solder it

Step3

 

There are 2 windings, each winding with 2 ends,total 4 ends,all Connect a wire

The paint is not conductive, so use a knife to scrape the paint

The 2 solar panels are a pair,

The anode of solar panel A is connected to the negative electrode of B plate,

Similarly, the negative electrode of the A plate is connected to the positive electrode of the B plate

 

C and D do the same thing

not clear?look at this picture again

 

Step4

Prepare double sided adhesive, at least 0.5mm thickness(Because the width of the solar panel is 25mm, the length of the plastic side is 24mm,So you need a thick double sided adhesive,If you don’t have it, please pad it with a piece of paper ,Compensating the gap of 0.5mm)

Handles the opposite sides first

For the sake of beauty, put messy wiring in the front

It’s time for uncertainty
C and D, which is on the left or on the right, we don’t know for sure, so it needs to be determined by experiments(In fact, it can be determined from the beginning, but if we start to consider the direction of the winding, it is more complex, so we completely ignore the direction, through the final experiment to determine the final installation position of the 2 solar panels, relatively simple and direct)

Not sure,so we start to try

first Find a rubber band,do not fix C and D with glue,Temporarily fixed with rubber band

Gap between compensation and magnet

 

 

Adjust the position of magnet,
So that he can levitate

 

if no sunshine,you can use a Incandescent lamp,plz do not use LED, fluorescent lamp(they can not work)

Do not wait it rotate,it wont,Poking with fingers,
See if there’s any sign of accelerated rotation
If there is, the position of C and D is determined, if not
Reverse direction, continue to observe

if still not

Change the direction of the light

do this again

Poking with fingers,
See if there’s any sign of accelerated rotation
If there is, the position of C and D is determined, if not
Reverse direction, continue to observe

 

After you try this,still not Accelerated rotation was observed,that is mean the C and D need exchange

so let us do this

change the position of C and D

 

ok,let us try again

this time we do as before,It speeds up spinning,so We’ve identified the positions of C and D and fixed them with glue

The hole will be a little tight,
Push it in(not push too hard,will break it.)

finally work

At last ,the Propeller!

 

Generally, there will be vibration at low speed, and when the speed increases, the vibration will disappear
If the vibration is too large, the rotating body will fly out, or because of vibration, can not be accelerated, need to be adjusted by adjustment

these 8 holes are for you putting the Counterweight(usually you  don’t need them,It’s just extreme situations)

OK,this project is finished,enjoy!
